RIVET-SFETTING MACHINE.

SPECIFICATION forming part of Letters Pgatent No. 416,282, datedDecember 3, 1889.

' Application filed March 13, 1889. fierial No. 303,170- (No model.)

constructed, arranged, and combined sulostantially as is hereindescribed and claimed.

In the accompanying sheets of drawings, Figure l is a front View, partlyin section, of the machine; Fig. 2, a side view, partly in section; Fig.3, a detail-in part section of the anvil in the planes 9c 00,. Fig. 2;Fig. 4, a

plan view of clamping-plate; Fig. 5, a plan view of receiver arm andplate; Fig. 6, an edge view of same; Fig. 7, aplan or top view ofreceiver and spring, and Fig. 8 a plan view of gage.

Similar letters of reference indicate like parts in the several views.

This invention relates especially to machines designed to secure buttonsto garments with a metal rivet or fastening. Machines for this purposein a general sense are well known, and it is common to provide suchmachines with hoppers, chutes, operating-levers, plungers, and receiversforthe rivets and anvils. These several features, combined andconstructed in different ways, are common to most machines of thischaracter.

In my improvement on this class of rivet.- setting machinesIconstructthe receiver-arm A with a plate B and pivot to the arm aclamping-plate O. The plate B at its front end is provided with acrotch-opening a and with a stop I). The clamping-plate C has pivoted toits upper surface the lever-bars 'c and d, the front ends of which formthe receiver D and the rear ends of which are provided with a spring 8.To the under side of the plate B is adjustably fitted, by means of aset-screw f and the slots 9 and h, a gageplate E, formed with lugs 76.Between the plates B andv C is fitted a spiral spring Z, and between theplate B and the base F of the machine is a spiral spring on. At theforward end of the base F is placed a telescopic anvil G, with a die ncentrally located therein. This die is adjustable with the aid of thescrew 0. In addition to these described parts, it is to be understoodthat my machine is provided with the ordinary rotating 110p- ;per, inwhich the rivets are placed in bulk to find their way thence by thechute H to the I receiver D, and that the machine is also provided witha plunger K and an operatinglever L.

In the operation of my machine, as before stated, the rivets which arepointed and headed find their way from a revolving hopper (not shown inthe drawings) to the receiver I) by way of the chute H. A but-ton,

with its hub uppermost, is placed on the anvil G. The garment or fabricfor which this button is intended is then placed between the plate B andthe clamping-plate C. The pointed rivet, which hasbeen lodged by gravitypoint downward in the receiver D, is driven through the receiver, thelever-bars c and (l spreading apart for that purpose, and the rivet isalso forced through an opening a" in the clamping-plate C. This opening7' is beveled somewhat, and although the head of a rivet may pass freelythrough the opening the sides thereof act to some degree as a steadierto keep the rivet in the desired perpendicular position. The rivet beingdriven by the action of the plunger K through the receiver D and throughthe opening 1 in the clamping-plate C, its point and shank are thrustthrough the fabric to which the button is to be attached, the fabricbeing placed, as stated, between-the plates B and O, the plate 0, as theplunger descends for the purpose of driving the rivet, yielding byreason of its hinged joint t and clamping by this action the fabricbetween the plates B and C, for an instant holding the fabric tight andsmooth, thereby insuring the penetration of the rivet not only trulythrough the fabric, but in the exact place intended. The rivet, in thisway forced through the fabric, is by the continued downward motion ofthe plunger carried, together with the fabric in which it is inserted,down to the button on the anvil G, when the point of the riveteuters ahole in the hub of the button, the anvil receding and permitting thepoint of the rivet to enter the die 71 within the anvil, in which diethe point is formed into a symmetrical head, and this head on one end ofthe rivet and the flange or head on the other end of the rivet fastenbetween them the button to the fabric. The operation above describedbeing finished, the plates B and C, by reason of the pivoted arm A, arerestored to their normal positions, ready for the next operation, by theaction of, the spiral spring 011., and by reason of the spring Z theplate 0 recovers its former position to admit the fabric between it andthe plate B.

To regulate the extent to which the fabric may be inserted between theplates B and C, a gage plate E is, by means of the setscrew f and theslots g and h,adj11sjably fitted to the under side of the plate B, sothat the lugs k on the gage-plate may admit the fabric to a greater orless extent between the plates; .and to prevent the accidental thrustingof the fabric beneath the plate B, instead of above it, a stop I) isfixed to the under side of the plate B for that purpose. The notchedopening a in the plate B permits the withdrawal of the fabric frombetween the plates B and C after the rivet and button have been fastenedto it, and the front side of the open ing 9' in the plate 0 may, ifdesired, be cut away, as is shown in Figs. 2 and 4, to enable theoperator to observe the position of the rivetwhen using the machine.

Having now described my invent-ion, whatI claim as new, and desire tosecure by Letters Patent, is-

1. In combination, in a rivet-setting machine, an arm A, pivoted to theframe of the machine, with aplate B fixed thereto, a clamplug-plate (I,pivoted to said arm, a receiver .1), with its lever-bars c and (Ipivoted to the upper surface of said clamping-plate (I, and an anvil G,as and for the purpose described.

2. In combination, in a rivet-setting machine, an operating-lever andplunger, a plate B, fixed to the. pivoted arm A, a clampingplate 0,hinged to said arm, a receiver 1), with pivoted lever-arms c 1?, springI between the plates B and O, and a spring at between the plate B andthe supporting-base of the machine, as and for the purpose described.

3. In a rivet-setting machine, a pla e B, constructed with a notchedopening a in its front end and with a stop I), and an adjustable gage E.secured to the said plate, as and for the purpose described.

t. In a rivet-setting machine, the combination of the plate B, connectedby a pivot with the frame of the machine, and the plate (3, pivoted tothe supporting-arm of the plate B and above the same and provided with areceiver D on its upper surface and with a beveled opening 7',constructed to operate snbstantially as and for the purpose described.

5. In a rivet-setting machine, the combination of the plate B, connectedbya pivot with the frame of the machine, an adjustable gage secured tothe plate B, and the plate 0, pivoted to the supporting-arm ot' theplate B and above the same and provided with a receiver D on its uppersurface and a beveled opening 1', the plate C being constructed to guidethe rivet and to be carried down by the action of the plunger and toclamp the fabric through which the rivet is thrust, substantial] y asand for the purpose described.
